That's because only a real artist knows the actual anatomy of the terrible or the physiology of fear - the exact sort of lines and proportions that connect up with latent instincts or hereditary memories of fright, and the proper colour contrasts and lighting effects to stir the dormant sense of strangeness.
Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species - if separate species we be - for its reserve of unguessed horrors could never be borne by mortal brains if loossed upon the world.
It is absolutely necessary, for the peace and safety of mankind, that some of earth's dark, dead corners and unplumbed depths be left alone; lest sleeping abnormalities wake to resurgent life, and blasphemously surviving nightmares squirm and splash out of their black lairs to newer and wider conquests.
My reason for writing stories is to give myself the satisfaction of visualising more clearly and detailedly and stably the vague, elusive, fragmentary impressions of wonder, beauty, and adventurous expectancy which are conveyed to me by certain sights (scenic, architectural, atmospheric, etc.), ideas, occurrences, and images encountered in art and literature.
There are not many persons who know what wonders are opened to them in the stories and visions of their youth; for when as children we listen and dream, we think but half-formed thoughts, and when as men we try to remember, we are dulled and prosaic with the poison of life.
Rome was so mighty that it could not fall. It had to vanish in a cloud, like so many of the mythical heros of antiquity, and to receive its apotheosis among the stars before men became fully aware that it had vanished from the earth!
Through the ghoul-guarded gateways of slumber, Past the wan-mooned abysses of night, I have lived o'er my lives without number, I have sounded all things with my sight.
I am so beastly tired of mankind and the world that nothing can interest me unless it contains a couple of murders on each page or deals with the horrors unnameable and unaccountable that leer down from the external universes.
I am distinctly opposed to visibly arrogant and arbitrary extremes of government--but this is simply because I wish the safety of an artistic and intellectual civilisation to be secure, not because I have any sympathy with the coarse-grained herd who would menace the civilisation if not placated by sops.
I have dwelt ever in realms apart from the visible world; spending my youth and adolescence in ancient and little-known books, and in roaming the fields and groves of the region near my ancestral home. I do not think that what I read in these books or saw in these fields and groves was exactly what other boys read and saw there; but of this I must say little, since detailed speech would but confirm those cruel slanders upon my intellect which I sometimes overhear from the whispers of the stealthy attendants around me.
It is because the cosmos is meaningless that we must secure our individual illusions of values, direction, and interest by upholding the artificial streams which give us such worlds of salutary illusion. That is - since nothing means anything in itself, we must preserve the proximate and arbitrary background which makes things around us seem as if they did mean something.
In theory I am an agnostic, but pending the appearance of rational evidence I must be classed, practically and provisionally, as an atheist. The chance's of theism's truth being to my mind so microscopically small, I would be a pedant and a hypocrite to call myself anything else.
Science, already oppressive with its shocking revelations, will perhaps be the ultimate exterminator of our human species - if separate species we be - for its reserve of unguessed horrors could never be borne by mortal brains if loossed upon the world.
